When websites say flu is endemic but covid-19 is pandemic, does that mean pandemic is the first year of outbreak and endemic are the years following?

Endemic: A disease that is permanently found in a region is called endemic to that region. Pandemic refers to an extremely widespread outbreak of a disease that affects many people over different regions at the same time.

No: A pandemic is widespread serious infection/ disease that has spread to many countries or multiple continents. Endemic means that a particular infection/ condition is regularly found in a particular area.
